Thanks to everyone that replied to this question, but I've run into a bit of
a stumbling block. It *appears* that I've gone and downloaded the src for
FreeBSD 5.0 rather than 4.7.
Apart from the obvious warning signs (NFS and MFS_ROOT being complained
about bitterly when you try a Kernel compile) is there any easy way to find
out what source code exists on a machine? Is the big caps lettering at the
top of README and UPDATE an indicator? Stop sniggering, this is my first
unix.
In terms of remedial measures, if I can locate exactly whats gone wrong with
my CVSUP file, can I just download the src tree again, or should I rm some
portion of it?
Ta.
